How to: Claude.ai mcp blockchain_fees__blockchain_fees_utxo

client:Claude.ai transport:streamable-http tool:blockchain_fees__blockchain_fees_utxo

Add mcp to Claude.ai

  1. 01

    Open Settings → Connectors → Add custom connector and merge this in. Keep any servers already there.

https://ai.cryptoapis.io/mcp
  1. 02

    Save the file and restart Claude.ai.

  2. 03

    Ask for something blockchain_fees__blockchain_fees_utxo does. Claude.ai lists the server's tools on connect and calls blockchain_fees__blockchain_fees_utxo itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that mcp's identifier in your config matches the one above exactly.

Claude on the web takes a remote URL and completes OAuth in the browser. For a packaged server use Claude Desktop or Claude Code instead. Claude.ai docs

Set these first

mcp will not start until these are set, so blockchain_fees__blockchain_fees_utxo never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 21 October 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
